TIME-CONTROLLED ELECTRIC DEVICE.

To all who?" it may concern:

Be it known that I, WALnnoN J. LUNGER,

a citizen of the United States, residing at Elm Creek, in the county of Buffalo and State of Nebraska, have invented certain new and useful Improvements in Time- Controlled Electric Devices, of which the following is a specification.

This invention relates to time controlled mechanisms and refers especially to an electric light and a gong circuit which is completed at predetermined times.

[in object of" this invention is to construct a device which is applicable to a clock of common structure and which will close a circuit to light an electric bulb or a gong at a distance from the clock automatically.

further object of the invention is to devise a mechanism of this character which is of simple structure and. comprises but few parts which are strong and durable so that a mechanism which is practical is obtained.

{Ether objects and advantages will be apparent from the following description. and it will be understood that changes in the speciiic structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in. which like numerals of reference indicate similar parts in the several views, Figure 1 is a rear elevation of a clock having the apparatus applied thereto, Fig. 2 is a view of the same showing the mechanism as being operated to close the circuit, Fig. 3 is a side elevation of the same showing the trip mechanism, Fig. 4 is a top plan view of the complete device, showing a diagrammatic view of the wiring.

Referring now to the drawings, designates a clock casing which is provided with a centrally and rearwardly extending shaft 11, the rear extremity of which supports a segmental disk 12 which is shouldered upon its outer edge as at 13 for the abutment of an arm 1.4 which is carried upon a wheel actuated by the clock 10. The arm 14 is adjustably secured upon the wheel 15 by means of a set screw 16 for the purpose of regulating the time at which the circuit is adapted to be closed. The disk 12 is provided with two contact pins 17 and 18 at the opposite e):- tremities thereof and upon the outer face which are connected by a copper wire 18 for the purpose of forming a current conductor between the two pins 17 and 18. The disk 12 Specification of Letters Patent.

Application filed. July 24, 1908.

is provided witn a spring 19 upon its outer face which is secured thereto by a pin 20, which spring is secured to the rear face of the clock by a pin 21 which holds the spring 1 9 under compression and causes the disk 12 to assume an upward position. The clock 10 carries two angular contact members 22 and 23 which extend rearwardly and inwardly over the edges of the disk 12 where they are positioned in the path of the contact pins 17 and 18 during the rotation of the disk 12 for the purpose of engaging the same at times to complete a circuit. he contact pin 22 is connected to one pole of a main circuit 24 which is connected at its other pole to a resette 25 where it is divided into a lamp circuit 26 and a bell circuit 27. The contact member 23 leads to a rosette 28 which is divided into two circuits 26 and 27 to complete the-circuit passing through the rosette 25. The bell circuit 27 is provided with a switch by which it may be broken so as to cause only the closing of the lamp circuit 26 upon the actuation of the mechanism. The wheel 15 is mounted upon a stub shaft 30 in the frame of the clock 10 which is connected to the clock mechanism and actuated thereby.

The operation of the device is as follows: Naen the clock is set in motion the wheel 1.5 is rotated and the arm 14 is carried thereby. V? ion the arm 14 protrudes from the rear face of the iasing it engages the shoulder aml carries the disk 12 downwardly against the tension of the spring 19. This action causes the contact pins 17 and 18 to travel about the shaft 1.1 and to be brought into contact with the members 22 and 23. The abutting of these contacts causes the circuits from the main circuit 24 to he formed through the member 22, contact pin 17, copper wire 18, contact pin 18 out of the member to the rosette 2S, thence through the two circuits 26 and 27 to the rosette 25 thence back to the main circuit 24. The circuit is closed until the arm 14 has traveled downwardly to a sufficient extent to disengage from the shoulder 13 and to allow the spring 19 to return the disk 12 to its normal position. If it is desired the bell circuit 27 may be broken by opening the switch 29 and the bell will not be affected by the operations of the disk 1.2. Any number of circuits may be formed between the rosettes 25 and28 as is desired as this device could be practically applied in hotels and the like where a bell or the like will be desired in each room. The memhers 22 and 23 must necessarily be of yield: able material and of sufficient length to allow for the movement of the disk 12 during the entire swinging of the arm 14 so as to prevent the breaking of the circuits.

This alarm device may he applied and operated by any alarm mechanism which is already mounted in clocks or mechanisms of a like nature. .fhe disk 12 may be actuated by the stationary key or the alarm mecl'ianism instead. of the arm 15. This device could he especially applied, to the alarm clock common structure w ich is provided with a stationary lzey with which to wind the alarm mechanism. This circuit closer ma y he made to light a plurality of miniature electric hullzs which may disposed ahout a clock face of any design adaptatle.

Vlhat is claimed is:

1. A device of the class described comprising a clock, a dish disposed upon the extension of a shaft of a clock, contact members disposed on said disk, contact memhers carried lay the clock, a shoulder on said disk, an arm carried by said clock for engagement at times against said shoulder for rotating said disk and bringing said contacts together and. circuits connected with said contacts.

2. A. device of the class described comprising a clock, a shaft rearwardly extended from said clock, a disk mounted on said shaft, a spring interposed between said disk and said clock for normally holding said disk in an upward position, a shoulder on said disk, an adjustable arm disposed on said clock for engagement with said shoulder, contact pins carried at the opposite ends of said disk, a wire disposed on said disk for connecting said pins, contact members disposed. on said clocl; for yieldalile engagement with said pins times and wires of electric circuits connected to said pins and contact members.

3. A device of the class described comprisl l l J ing a clock, a shaft rearwardly extended from said clock, a disk loosely disposed on said shaft a spring carried oetween said disk and said clocl: for holding said disk in its normal position, two contact pins disposed at the opposite end of said disk, a wire disposed on said disk oetween said pins, a wheel carried by said clock and actuated thereby, an adjustahle arm disposed on said wheel, a shoulder on said disk, said arm adapted to engage at times against said shoulder to operate said disk and contact members disposed. said clock for yieldahle engagement against said pins when said dish is rotated. 4.
